BACKGROUND OF THE INVENTIONBACKGROUND OF THE INVENTION

Multi-epitope vaccines [0002] It is known that B-cell epitopes, T-helper cell epitopes, and cytotoxic T lymphocytes epitopes all play important roles in these two immune responses. Obviously, broad spectrum and long lasting humoral and cellular responses should be induced for effective vaccination. There are still no broad spectrum and effective vaccines against viruses with high mutation rates, such as influenza virus and human immunodeficiency virus.Multi-epitope vaccines It is known that B-cell epitopes, T-helper cell epitopes, and cytotoxic lymphocytes epitopes all play important roles in these two immune responses. Obviously, broad spectrum and long-lasting humoral responses should be induced for effective vaccination. Influenza viruses and human immunodeficiency viruses.

[0003] There is a close relationship between antigen dose and the efficiency of the specific B-cell response. Studies using a chemically coupled carrier protein and epitope peptide system, consisting of the same amount of carrier protein coupled with varying amounts of epitope peptide, have shown that epitope density dramatically affected T helper cell-dependent IgG responses (Jegerlehner et al., Eur J Immunol. 2002, 32:3305-14). Liu et al. (Vaccine. 2004 23(3):366-71.) observed a positive effect of epitope density on the humoral response of mice and rabbits immunized with glutathione-S-transferase fusion proteins bearing various numbers of copies of the M2e peptide epitope (1,2, 4, 8, and 16 copies) of the M2 protein of the influenza virus. In the same study, a lethal challenge assay showed that the fusion protein with the higher epitopes densities resulted in higher survival rates and slower weight losses.There is also a B-cell response. The use of cell-dependent IgG responses (Jegerlehner et al., Eur J, et al. Immunol. 2002, 32: 3305-14). Liu et al. (Vaccine. 2004 23 (3): 366-71) Immunized with glutathione-S-transferase fusion proteins (1) , 2, 4, 8, and 16 copies of the M2 protein of the influenza virus. In the same study, lethal challenge assay showed that the fusion protein was the highest in the body.

Influenza [0006] Influenza is a disease caused by viruses of three main subtypes, Influenza A, B and C, which are classified according to their antigenic determinants. The influenza virion consists of a single stranded RNA genome closely associated with a nucleoprotein (NP) and enclosed by a lipoprotein envelope lined by matrix protein (M1) and carrying two major surface glycoprotein antigens, haemagglutinin (HA) and neuraminidase (NA). The HA and NA glycoproteins are most susceptible to change; for example, there are 16 immune classes of HA and 9 different NA classes that provide the basis for the different influenza virus subtypes like H1N1 or H3N2. Influenza A virus has an additional transmembrane glycoprotein, M2, which is highly conserved between the different HN subtypes. The M2 gene encodes a protein having 96-97-amino-acids that is expressed as a tetramer on the virion cell surface. It is composed of about 24 extracellular amino acids, about 19 transmembrane amino acids, and about 54 cytoplasmic residues (Lamb et al, Cell. 1985; 40:627-633.).Influenza is a disease caused by viruses of three main subtypes, Influenza A, B and C, which are classified according to their antigenic determinant.

[0007] Influenza A and B viruses are the most common causes of influenza in man. Influenza has an enormous impact on public health with severe economic implications in addition to the devastating health problems, including morbidity and even mortality. Infection may be mild, moderate or severe, ranging from asymptomatic through mild upper respiratory infection and tracheobronchitis to a severe, occasionally lethal, viral pneumonia. Influenza viruses have two important immunological characteristics that present a challenge to vaccine preparation. The first concerns genetic changes that occur in the surface glycoproteins every few years, referred to as "antigenic drift". This antigenic change produces viruses that elude resistance elicited by existing vaccines. The second characteristic of great public health concern is that influenza viruses, in particular influenza A virus can exchange genetic material and merge. This process, known as "antigenic shift", results in new strains different from both parent viruses, which can be lethal pandemic strains.Influenza A and B viruses are the most common causes of influenza in man.

Influenza Virus Antigens and Vaccine Production [0008] Immunization towards influenza virus is limited by the antigenic variation of the virus and by the restriction of the infection to the respiratory mucous membranes. The influenza vaccines currently available are based either on whole inactive virus, on viral proteins presented on the surface of bacterial cells, or on flagellin bearing viral antigenic determinants. HA is a strong immunogen and is the most significant antigen in defining the serological specificity of the different virus strains.Influenza Virus Antigens and Vaccine Production Immunization towards influenza virus is limited by the antigenic variation of the virus.

DETAILED DESCRIPTION OF THE INVENTIONDETAILED DESCRIPTION OF THE INVENTION

[0027] The present invention provides multimeric multiepitope polypeptides and vaccines based on these polypeptides, comprising a plurality of influenza virus peptide epitopes as defined by the claims. The present invention also provides vaccines based on such polypeptides and uses thereof.The present invention provides multimeric multiepitope polypeptides and vaccines based on these polypeptides, as defined by the claims. The present invention also relates to such polypeptides and uses.

[0028] Peptide epitopes derived from influenza proteins are useful in preparing vaccines against influenza. However, each peptide alone is almost invisible to the immune system, is degraded rapidly and arouses an insufficient immune response. When multiple copies of immunogenic peptides are presented to the immune system as single polypeptide, the magnitude of the epitope-specific immune response is enhanced. For example, vaccines based on a recombinant flagellin fusion protein containing a single copy of one influenza peptide epitope provide an epitope/flagellin ratio of approximately 1:28. By using multi-epitope vaccines, containing a plurality of epitopes in several copies each, a epitope/flagellin ratio of up to 2:1 can be obtained. The present invention discloses multimeric multiepitope polypeptides with enhanced immunogenicity compared to the known constructs and configurations. The polypeptides each contain a plurality of epitopes, wherein each epitope is repeated in multiple copies. The multiple copies or repeats of each epitope may be contiguous as a block of each epitope. Alternatively the plurality of epitopes may appear in a predetermined sequence where this sequence is repeated a number of times within the polypeptide. Both these types of configurations of the multiple epitopes are now shown to have unexpectedly superior results in conferring immunity against influenza on a subject.[0028] Peptide epitopes derived from influenza are useful in preparing vaccines against influenza.

The host cells which express the recombinant flagellin fusion protein can be formulated as live vaccines.

Production of the Multimeric Polypeptide [0052] Once expressed by the host cell, the multimeric polypeptide can be separated from undesired components by a number of protein purification methods. One such method uses a polyhistidine tag on the recombinant protein. A polyhistidine-tag consists in at least six histidine (His) residues added to a recombinant protein, often at the N- or C-terminus. Polyhistidine-tags are often used for affinity purification of polyhistidine-tagged recombinant proteins that are expressed in E. coli or other prokaryotic expression systems. The bacterial cells are harvested by centrifugation and the resulting cell pellet can be lysed by physical means or with detergents or enzymes such as lysozyme. The raw lysate contains at this stage the recombinant protein among several other proteins derived from the bacteria and are incubated with affinity media such as NTA-agarose, HisPur resin or Talon resin. These affinity media contain bound metal ions, either nickel or cobalt to which the polyhistidine-tag binds with micromolar affinity. The resin is then washed with phosphate buffer to remove proteins that do not specifically interact with the cobalt or nickel ion. The washing efficiency can be improved by the addition of 20 mM imidazole and proteins are then usually eluted with 150-300 mM imidazole. The polyhistidine tag may be subsequently removed using restriction enzymes, endoproteases or exoproteases. Kits for the purification of histidine-tagged proteins can be purchased for example from Qiagen.Production of the Multimeric Polypeptide Once expressed by the host cell, the multimeric polypeptide can be separated from the cells.

[0053] Another method is through the production of inclusion bodies, which are inactive aggregates of protein that may form when a recombinant polypeptide is expressed in a prokaryote. While the cDNA may properly code for a translatable mRNA, the protein that results may not fold correctly, or the hydrophobicity of the added peptide epitopes may cause the recombinant polypeptide to become insoluble. Inclusion bodies are easily purified by methods well known in the art. Various procedures for the purification of inclusion bodies are known in the art. The inclusion bodies may be recovered from bacterial lysates by centrifugation and are washed with detergents and chelating agents to remove as much bacterial protein as possible from the aggregated recombinant protein. To obtain soluble protein, the washed inclusion bodies are dissolved in denaturing agents and the released protein is then refolded by gradual removal of the denaturing reagents by dilution or dialysis (as described for example in Molecular cloning: a laboratory manual, 3rd edition, Sambrook, J. and Russell, D. W., 2001; CSHL Press).Another method is by way of a recombinant polypeptide is expressed in a prokaryote.

[0061] Liposomes provide another delivery system for antigen delivery and presentation. Liposomes are bilayered vesicles composed of phospholipids and other sterols surrounding a typically aqueous center where antigens or other products can be encapsulated. The liposome structure is highly versatile with many types range in nanometer to micrometer sizes, from about 25 nm to about 500 μηι. Liposomes have been found to be effective in delivering therapeutic agents to dermal and mucosal surfaces. Liposomes can be further modified for targeted delivery by for example, incorporating specific antibodies into the surface membrane, or altered to encapsulate bacteria, viruses or parasites. The average survival time or half life of the intact liposome structure can be extended with the inclusion of certain polymers, for example polyethylene glycol, allowing for prolonged release in vivo. Liposomes may be unilamellar or multilamellar.Liposomes provide another delivery system for antigen delivery and presentation.

The average survival time or half life of the intact liposome can be extended in vivo. Liposomes may be unilamellar or multilamellar.

[0062] The vaccine composition may be formulated by: encapsulating an antigen or an antigen/adjuvant complex in liposomes to form liposome-encapsulated antigen and mixing the liposome-encapsulated antigen with a carrier comprising a continuous phase of a hydrophobic substance. If an antigen/adjuvant complex is not used in the first step, a suitable adjuvant may be added to the liposome-encapsulated antigen, to the mixture of liposome-encapsulated antigen and carrier, or to the carrier before the carrier is mixed with the liposome-encapsulated antigen. The order of the process may depend on the type of adjuvant used. Typically, when an adjuvant like alum is used, the adjuvant and the antigen are mixed first to form an antigen/adjuvant complex followed by encapsulation of the antigen/adjuvant complex with liposomes. The resulting liposome-encapsulated antigen is then mixed with the carrier. The term "liposome-encapsulated antigen" may refer to encapsulation of the antigen alone or to the encapsulation of the antigen/adjuvant complex depending on the context. This promotes intimate contact between the adjuvant and the antigen and may, at least in part, account for the immune response when alum is used as the adjuvant. When another is used, the antigen may be first encapsulated in liposomes and the resulting liposome-encapsulated antigen is then mixed into the adjuvant in a hydro-phobic substance.The vaccine composition may be formulated by: liposome-encapsulated antigen and adjuvant liposome-encapsulated antigen with a carrier phase of a hydrophobic substance. If an antigen / adjuvant complex is not used in a liposome-encapsulated antigen, a mixture of liposome-encapsulated antigen and carrier, or the carrier is mixed with the liposome. -encapsulated antigen. The order of the process may be the type of adjuvant used. Typically, as an adjuvant, the adjuvant and the antigen are adjuvant complexes with an antigen / adjuvant complex with liposomes. The resulting liposome-encapsulated antigen is then mixed with the carrier. The term "liposome-encapsulated antigen" may refer to the antigen / adjuvant complex depending on the context. This adjuvant is an adjuvant and the antigen and may be used as an adjuvant. The liposome-encapsulated antigen is then mixed with the adjuvant in a hydro-phobic substance.

[0063] In formulating a vaccine composition that is substantially free of water, antigen or antigen/adjuvant complex is encapsulated with liposomes and mixed with a hydrophobic substance. In formulating a vaccine in an emulsion ofwater-in-a hydrophobic substance, the antigen or antigen/adjuvant complex is encapsulated with liposomes in an aqueous medium followed by the mixing of the aqueous medium with a hydrophobic substance. In the case of the emulsion, to maintain the hydrophobic substance in the continuous phase, the aqueous medium containing the liposomes may be added in aliquots with mixing to the hydrophobic substance.[0063] The formulation of a vaccine composition that is free of water is an antigen or antigen / adjuvant complex that is encapsulated with liposomes and mixed with a hydrophobic substance. Inoculum of a hydrophobic substance, an antigen or antigen / adjuvant complex is encapsulated with a hydrophobic substance. In the case of the emulsion, the substance is in the phase of the hydrophobic substance.

[0064] In all methods of formulation, the liposome-encapsulated antigen may be freeze-dried before being mixed with the hydrophobic substance or with the aqueous medium as the case may be. In some instances, an antigen/adjuvant complex may be encapsulated by liposomes followed by freeze-drying. In other instances, the antigen may be encapsulated by liposomes followed by the addition of adjuvant then freeze-drying to form afreeze-dried liposome-encapsulated antigen with external adjuvant. In yet another instance, the antigen may be encapsulated by liposomes followed by freeze-drying before the addition of adjuvant. Freeze-drying may promote better interaction between the adjuvant and the antigen resulting in a more efficacious vaccine.[0064] The liposome-encapsulated antigen may be freeze-dried before being mixed with the hydrophobic substance or with the aqueous medium as the case may be. In some instances, an antigen / adjuvant complex may be encapsulated by liposomes followed by freeze-drying. In other instances, the antigen may be encapsulated by the adjuvant and freeze-drying liposome-encapsulated antigen with external adjuvant. In yet another instance, the antigen may be encapsulated by liposomes. Freeze-drying may result in a more efficacious vaccine.

[0065] Formulation of the liposome-encapsulated antigen into a hydrophobic substance may also involve the use of an emulsifier to promote more even distribution of the liposomes in the hydrophobic substance. Typical emulsifiers are well-known in the art and include mannide oleate (Arlacel™ A), lecithin, Tween™ 80, Spans™ 20, 80, 83 and 85.

[0066] Microparticles and nanoparticles employ small biodegradable spheres which act as depots for vaccine delivery. The major advantage that polymer microspheres possess over other depot-effecting adjuvants is that they are extremely safe and have been approved by the Food and Drug Administration in the US for use in human medicine as suitable sutures and for use as a biodegradable drug delivery system (Langer R. Science. 1990; 249(4976):1527-33). The rates of copolymer hydrolysis are very well characterized, which in turn allows for the manufacture of microparticles with sustained antigen release over prolonged periods of time (O’Hagen, et al., Vaccine. 1993;11(9):965-9).Microparticles and nanoparticles employ small biodegradable spheres which act as depots for vaccine delivery. The major advantage of the polymer microspheres is that they are extremely safe and effective. Langer R. Science. 1990; 249 (4976): 1527-33). (O'Hagen, et al., Vaccine. 1993; 11 (9): 965-9) .

[0067] Parenteral administration of microparticles elicits long-lasting immunity, especially if they incorporate prolonged release characteristics. The rate of release can be modulated by the mixture of polymers and their relative molecular weights, which will hydrolyze over varying periods of time. Without wishing to be bound to theory, the formulation of different sized particles (1 μηη to 200 μηι) may also contribute to long-lasting immunological responses since large particles must be broken down into smaller particles before being available for macrophage uptake. In this manner a single- injection vaccine could be developed by integrating various particle sizes, thereby prolonging antigen presentation and greatly benefiting livestock producers.Parenteral administration of microparticles elicits long-lasting release characteristics.

In this continent a single-injection vaccine could be developed by integrating various particle sizes.

[0068] In some applications an adjuvant or excipient may be included in the vaccine formulation. Montanide™ (Incomplete Freund’s adjuvant) and alum for example, are preferred adjuvants for human use. The choice of the adjuvant will be determined in part by the mode of administration of the vaccine. For example, non-injected vaccination will lead to better overall compliance and lower overall costs. A preferred mode of administration is intramuscular administration. Another preferred mode of administration is intranasal administration. Non-limiting examples of intranasal adjuvants include chitosan powder, PLA and PLG microspheres, QS-21, calcium phosphate nanoparticles (CAP) and mCTA/LTB (mutant cholera toxin E112K with pentameric B subunit of heat labile enterotoxin).In some applications, the adjuvant or excipient may be included in the vaccine formulation.

The proteosome adjuvant comprises a purified preparation of outer membrane proteins of meningococci and similar preparations from other bacteria. These proteins are highly hydrophobic, reflecting their role as transmembrane proteins and pori ns. Due to their hydrophobic protein-protein interactions, when appropriately isolated, the proteins form multimolecular structures consisting of about 60-100 nm diameter whole or fragmented membrane vesicles. This liposome-like physical state allows the proteosome adjuvant to act as a protein carrier and also to act as an adjuvant.The multimeric multiepitope polypeptides of the present invention may be described by several specific embodiments of a proteosome adjuvant.

These proteins are highly hydrophobic, reflecting their role as transmembrane proteins and pori ns. 60 to 100 nm diameter whole or fragmented membrane vesicles. This is a liposome-like physical state that can be used as an adjuvant.

[0086] The use of proteosome adjuvant has been described in the prior art and is reviewed by Lowell GH in "New Generation Vaccines", Second Edition, Marcel Dekker Inc, New York, Basel, Hong Kong (1997) pages 193-206. Proteosome adjuvant vesicles are described as comparable in size to certain viruses which are hydrophobic and safe for human use. The review describes formulation of compositions comprising non-covalent complexes between various antigens and proteosome adjuvant vesicles which are formed when solubilizing detergent is selectably removed using exhaustive dialysis technology.The use of proteosome adjuvant has been described in the prior art and Lowell GH in "New Generation Vaccines", Second Edition, Marcel Dekker Inc, New York, Basel, Hong Kong (1997) pages 193-206.

Non-covalent complexes between various antigens and proteosome adjuvant vesicles, which are formed by the use of exhaustive dialysis technology.

[0087] The polypeptides of the present invention are optionally complexed to the proteosome antigen vesicles through hydrophobic moieties. For example, an antigen is conjugated to a lipid moiety such as a fatty acyl group. Such a hydrophobic moiety may be linked directly to the multimeric polypeptide or alternatively, a short spacer, for example, of one, two, three or four, up to six or ten amino acids can be used to link the multimeric polypeptide to the fatty group. This hydrophobic anchor interacts with the hydrophobic membrane of the proteosome adjuvant vesicles, while presenting the generally hydrophilic antigenic peptide.The polypeptides of the present invention are complexed to the proteosome antigen vesicles through hydrophobic moieties.

This hydrophobic anchor interact with the hydrophobic membrane of the proteosome adjuvant vesicles, while presenting the generally hydrophilic antigenic peptide.

[0088] In particular, a hydrophobic anchor may comprise a fatty acyl group attached to the amino terminus or near the carboxyl terminus of the multimeric polypeptide. One example is the twelve-carbon chain lauroyl (CH3(CH)10CO), although any similarly serving fatty acyl group including, but not limited to, acyl groups that are of eight-, ten-, fourteen-, sixteen-, eighteen-, or twenty-carbon chain lengths can also serve as hydrophobic anchors. The anchor may be linked to the peptide antigen using an immunopotentiating spacer. Such a linker may consist of 1-10 amino acids, which may assist in maintaining the conformational structure of the peptide.In particular, the hydrophobic anchor may be a fatty acyl group attached to the amino terminus of the multimeric polypeptide.

The detergent-based solutions of the two components may contain the same detergent or different detergents and more than one detergent may be present in the mixture subjected to uItrafiItration/diafiItration. Suitable detergents include Triton, Empigen and Mega-10. Other suitable detergents can also be used. The detergents serve to solubilise the components used to prepare the composition.The two components, which are the multimeric polypeptides and the proteosome adjuvant may be formulated by a method of detergent (s) and then removing the detergent (s) by diafiltration / ultrafiltration methods.

[0091] Whereas commercial influenza vaccine that are produced in eggs induce allergy in individuals that are sensitive to hen eggs, the multimeric vaccine did not elicit such responses as manifested by IgE titer before and after immunization.[0091] Influenza vaccines that are produced in eggs are induce allergy to individuals that are susceptible to infection.

[0092] The antigen content is best defined by the biological effect it provokes. Naturally, sufficient antigen should be present to provoke the production of measurable amounts of protective antibody. A convenient test for the biological activity of viruses involves the ability of the antigenic material undergoing testing to deplete a known positive antiserum of its protective antibody. The result is reported in the negative log of the LD50 (lethal dose, 50%) for mice treated with virulent organisms which are pretreated with a known antiserum which itself was pretreated with various dilutions of the antigenic material being evaluated. A high value is therefore reflective of a high content of antigenic material which has tied up the antibodies in the known antiserum thus reducing or eliminating the effect of the antiserum on the virulent organism making a small dose lethal. It is preferred that the antigenic material present in the final formulation is at a level sufficient to increase the negative log of LD50 by at least 1 preferably 1.4 compared to the result from the virulent organism treated with untreated antiserum. The absolute values obtained for the antiserum control and suitable vaccine material are, of course, dependent on the virulent organism and antiserum standards selected.The antigen content is the best defined by the biological effect it provokes. Naturally, sufficient antigen should be present. A convenient test of the viruses is the ability of the antigenic material to undergo testing for a positive antiserum of its protective antibody. The result is reported in the LD50 (lethal dose, 50%) for mice treated with a virulent organism which is pretreated with various dilutions of the antigenic material being evaluated. A small dose lethal. A high value is therefore a reflective of the antiserum. It is an antisense antiserum. Control and suitable vaccine material are, of course, dependent on the virulent organism and antiserum standards selected.

[0093] The following method maybe also used to achieve the ideal vaccine formulation: starting from a defined antigen, which is intended to provoke the desired immune response, in a first step an adjuvant matched to the antigen is found, as described in the specialist literature, particularly in WO 97/30721. In a next step the vaccine is optimized by adding various isotonic-making substances as defined in the present inventions, preferably sugars and/or sugar alcohols, in an isotonic or slightly hypotonic concentration, to the mixture of antigen and adjuvant, with the composition otherwise being identical, and adjusting the solution to a physiological pH in the range from pH 4.0 to 10.0, particularly 7.4. Then, in a first step the substances or the concentration thereof which will improve the solubility of the antigen/adjuvant composition compared with a conventional, saline-buffered solution are determined. The improvement in the solubility characteristics by a candidate substance is a first indication that this substance is capable of bringing about an increase in the immunogenic activity of the vaccine.[0093] The following method is also used to determine the desired antigen response, which is in the first step of the invention. literature, particularly in WO 97/30721. In an isotonic or slightly hypotonic concentration, in the isotonic or slightly hypotonic concentration, with the composition otherwise being identical, and adjusting to the physiological pH in the range from 4.0 to 10.0, especially 7.4. Then, in a first step, a saline-buffered solution is determined. The remedy for the vaccine is that of the vaccine.

[0094] Since one of the possible prerequisites for an increase in the cellular immune response is increased binding of the antigen to APCs (antigen presenting cells), in a next step an investigation can be made to see whether the substance leads to an increase of this kind. The procedure used may be analogous to that described in the definition of the adjuvant, e.g. incubating APCs with fluorescence-labelled peptide or protein, adjuvant and isotonic-making substance. An increased uptake or binding of the peptide to APCs brought about by the substance can be determined by comparison with cells which have been mixed with peptide and adjuvant alone or with a peptide/adjuvant composition which is present in conventional saline buffer solution, using throughflow cytometry.[0094] Since one of the possible prerequisites for an increase in antigenic response is the antigen presenting cells, this kind. The procedure used may be analogous to that in the definition of the adjuvant, e.g. incubating APCs with fluorescence-labeled peptide or protein, adjuvant and isotonic-making substance. An increased uptake or binding of the peptide to the peptide and adjuvant alone with a peptide / adjuvant composition which is present in a conventional saline buffer solution, using throughflow cytometry .

[0095] In a second step the candidate substances may be investigated in vitro to see whether and to what extent their presence is able to increase the presentation of a peptide to APCs; the MHC concentration on the cells may be measured using the methods described in WO 97/30721 for testing peptides.[0095] In a second step, the present invention is contemplated as to the scope of the present invention. MHC concentration in the cells may be measured using the methods described in WO 97/30721 for testing peptides.

[0096] Another possible way of testing the efficiency of a formulation is by using an in vitro model system. In this, APCs are incubated together with adjuvant, peptide and candidate substance and the relative activation of aT-cell clone which specifically recognizes the peptide used is measured (Coligan et al., 1991 ; Lopez et al., 1993).[0096] Another way of testing is the use of an in vitro model system. In this, APCs are incubated, as well as peptide and peptide applications (Coligan et al., 1991; Lopez et al., 1993).

[0097] The efficiency of the formulation may optionally also be demonstrated by the cellular immune response by detecting a "delayed-type hypersensitivity" (DTH) reaction in immunized animals.The delayed-type hypersensitivity (DTH) reaction in immunized animals.

[0122] The purified vaccine is used in several mice models to establish its efficacy, mechanism of action and preliminary toxicology data prior to the repeated dose toxicology. The humoral response as well as pharmacodynamics studies are performed in several strains of mice. One animal model that is employed for the evaluation of the vaccine is the transgenic mice for HLA A*0201.

The mice were vaccinated intramuscularly three times with 3 weeks interval with a dose of 150 mcg/mouse of vaccines #11, #12 and #14 with and without adjuvant (IFA). Three to four weeks after the last immunization, the mice were infected with a 300 LD50 of a mouse adapted influenzavírus H3N2 strain (A/Texas/1/77).

The mice were vaccinated intramuscularly three times with a dose of 150 mcg / mouse of vaccine # 11, # 12 and # 14 with and without adjuvant (IFA). Influenza virus H3N2 strain (A / Texas / 1/77) was 300 LD50. Five days post infection, the survival rate was monitored. Treated and control groups immunized with 50% glycerol in PBS with and without IFA were compared.

The viral load in the groups where 100% survival was found is significantly lower than the viral load in the control groups (p<0.05). Due of the small number of mice per group (5 mice), the statistical analysis was done using Two-sided Fisher’s Exact Test. P value of 5% or less is considered statistically significant. The data was analyzed using the SAS® version 9.1 (SAS Institute, Cary North Carolina).The viral load in their lungs is detailed in figure 6B for vaccines # 11 and # 14 only. 100% survival was found in the control groups (p <0.05).

Example 9: Repeated dose toxicology [0127] Repeated dose toxicology trials are performed with vaccine #14 (Multimeric vaccine in three block repeats suspended in 50% Glycerol in PBS or in Incomplete Freund’s adjuvant, according a protocol based on: http://www3.ni- aid.nih.gov/daids/vaccine/Science/VRTT/06_SafetyTest.htm.Example 9: Repeated dose toxicology Reproduced dose toxicology studies performed with vaccine # 14 (Multimeric vaccine in a block of 50% Glycerol in PBS or in Incomplete Freund's adjuvant, according to a protocol based on: http: // www3) .ni- aid.nih.gov/daids/vaccine/Science/VRTT/06_SafetyTest.htm.

[0128] A preliminary dose related toxicology study is performed in ICR outbred mice. Three animals per gender per dose for each time point of sacrifice are employed to test the histopathology of their major organs following intramuscular administration of the vaccine one, two and three times.A preliminary dose related toxicology study is performed in ICR outbred mice. Three animals per gender for each time point of the histopathology of the major organs of the vaccine one, two and three times.

[0129] The highest dose intended for the clinic is employed in a 6-week repeat dosing containing three fortnightly vaccinations is likely to be sufficient to assess the toxicity of the product and enable two repeated. The studies include monitoring the in-live stage followed by a full range of toxicological parameters, including necropsy and full histopatho-logical examination of all major organs on days 2 days and 2 weeks post immunization in order to demonstrate that any toxicological effects seen during the treatment period were reversible.The highest dose for the clinic is the six-week repeat dosing containing three cases. The studies include monitoring of the in-live stage, including a full range of histopathological tests, and full histopathology. treatment period were reversible.

Example 10: Phase l/lla clinical trial [0130] The primary objective of this clinical study is to examine safety of the preventive anti-influenza vaccine after a single or double intramuscular administration. The study is conducted under controlled clinical settings among healthy volunteers aged from 18 years old to 49 years old. The secondary objective is to estimate the immunogenicity induced by administration of the multimeric vaccine. This phase l/ll study assesses the most common acute adverse effects and examines the size of doses that patients can take safely without a high incidence of side effects.Example 10: Phase l / il clinical trial [0130] \ t The study is conducted under controlled clinical conditions from 18 years old to 49 years old. The secondary objective is the immunogenicity of the multimeric vaccine. This study is designed to evaluate the effects of the disease.

Example 11 : Anti viral response in mice sera immunized with commercial influenza vaccine followed by immunization with Multimeric vaccine [0131] Transgenic mice for HLA A*0201 were immunized with the commercial inactivated influenza vaccine (split virion) BP Vaxigrip® three times, on days 0, 60, 81, or with Vaxigrip® once, on day 0, and 2 additional immunizations (on days 60 and 81) with the Multimeric vaccines #11, #12 and #14. Blood collection was performed before immunization (pre immune) and after the last immunization. Antibodies to several influenza strains were determined in pooled sera: H3N2: A/Wisconsin/67/05, A/Texas/1/77, A/California/07/2007, A/Fujian/411/2002, A/Moscow/10/99 and A/Pana-ma/2007/99; H1N1: A/New Caledonia/20/99, A/WSN/33, A/PR8/34 B: B/Malaysia/2506/04, B/Lee/40.Example 11: Transgenic mice for HLA A * 0201 were immunized with the commercial inactivated influenza vaccine (split virion) BP Vaxigrip® three times, on days 0, 60, 81, or with Vaxigrip® once, on day 0, and 2 additional immunizations with on Multimeric vaccines # 11, # 12 and # 14. Blood collection was performed before immunization and after the last immunization. Antibodies to several influenza strains were determined in half sera: H3N2: A / Wisconsin / 67/05, A / Texas / 1/77, A / California / 07/2007, A / Fujian / 411/2002, A / Moscow / 10 / 99 and A / Pana-ma / 2007/99; H1N1: A / New Caledonia / 20/99, A / WSN / 33, A / PR8 / 34B: B / Malaysia / 2506/04, B / Lee / 40.

[0132] After the first immunization with Vaxigrip®, which is intended for a single immunization in human, there was no significant elevation in titers to all of the viruses (except of x4 fold titer elevation to A/California).After the first immunization with Vaxigrip®, which is intended for a single immunization in humans, there was no significant elevation in the viruses (except for the x4 fold titer elevation to A / California).

[0133] The results are shown in tables 5Aand 5B. With the Multimeric formulations, prior immunization with Vaxigrip® did not significantly elevated the response to the viruses as compared to other data from immunization studies where similar humoral responses were demonstrated. A maximum of 8 times elevation in titers of post/pre immune was observed after two immunizations with the Multimeric vaccine. Control group administered with PBS was negative to all viruses. In the comparison of the different multimeric variants, #14 was the best candidate in terms of humoral response to viruses.[0133] Table 5Aand 5B. With the Multimeric Formulations, Prior Immunization with Vaxigrip® did not have much to do with data from immunization studies. The maximum of 8 times elevation in post-immunization with the Multimeric vaccine. Control group administered with PBS was negative to all viruses. In the comparison of the different multimeric variants, # 14 was the best candidate in the field of humoral response to viruses.
